BACKGROUND OF THE INVENTION

(1) Field of the Invention

The present invention discloses through-hole vertical semiconductor devices or chips comprising through-hole vertical semiconductor GaN based, GaP based, GaNP based and ZnO based devices or chips (comprising through-hole vertical GaN based, GaP based, GaNP based and ZnO based LED) and low cost methods of manufacturing the same.

(2) Prior Art

High power semiconductor devices or chips comprising GaN based, GaP based, GaNP based and ZnO based devices or chips (comprising GaN based, GaP based, GaNP based and ZnO based LEDs) have huge market. However, (1) technical and manufacturing issues (including heat dissipation and yield) need to be resolved; (2) performance and reliability need to be continuously improved; (3) products become smaller, thinner and lighter. In order to resolve the issues mentioned above, several methods have been disclosed, comprising: (1) vertical GaP based LED chips are disclosed to resolve the absorption of emitting light of GaAs growth substrate; (2) vertical GaN based LED are disclosed to resolve the low heat dissipation of sapphire growth substrates. The basic manufacturing process and structure of vertical semiconductor devices or chips are the following: depositing a reflector/Ohmic/bonding layer on the epitixial layer of a semiconductor epitixial wafer, bonding the reflector/Ohmic/bonding layer to an electrically conductive supporting substrate, removing the original growth substrate, depositing electrodes on the exposed epitaxial layer to form vertical semiconductor chips. However there is at least one wire to be bonded to a vertical chip for connecting the chip to an external power source. Wire bonding causes reliability issue, thicker packages and complicated packaging process. Also burn-in process has to be done after packaging the chips, which causes uncertainty of chip quality before packaging. Once the chip is not qualified, then the whole package is failed and hard to re-work, and the cost is increasing.

The present invention discloses a through-hole vertical semiconductor devises or chips with or without static protection diodes and methods of manufacturing the same.

Since a wafer includes a plurality of same chips or     devices, in FIG. 1 and FIG. 3, using one chip or device to     illustrate the manufacturing process. -   (6) A metalized supporting wafer has the same size as that of the     semiconductor epitaxial wafer.
